多要素認証

たようそにんしょう · Multi-factor authentication

Also known as: 多段階認証

An authentication method that requires two or more factors from different categories — knowledge (password, security questions), possession (smartphone, IC card, hardware token), and biometrics (fingerprint, face, iris) — to verify identity. Because a single compromised factor is not sufficient for unauthorized login, security is significantly improved. SMS-based authentication is a typical example of a possession factor using a smartphone.
